Çok aşamalı su terfi istasyonlarının enerji maliyeti yönünden optimum işletimi için yeni bir yaklaşım.

It is important to make improvements for the optimum operation of water pumping stations in order to reduce energy costs while meeting water demand continuously. In this article, a new algorithm (OSDPA-optimal simplified dynamic programming algorithm) has been developed by optimizing the previously developed SDPA (simplified dynamic programming algorithm) approach. The SDPA approach is most effective with straightforward systems, whereas the OSDPA approach is versatile, suitable for optimizing both simple and multi-stage, complex pumping systems. A water supply system with a multi-stage structure for Sakarya Water and Sewerage Administration (SASKİ) in Turkey has been used as a case study. The results show that the OSDPA approach can be quite successful in shifting the loads in the time period (peak) where the unit price is expensive to the time periods (night and day) where the unit price is cheaper. When compared with the conventional water level control (CWLC) approach, while SDPA saves about 18% for pump C in the second stage, about 22% for pump B, and about 19% for pump A in the first stage; OSDPA saved 39% for C pump, 41% for B pump and 24% for A pump.
